MARK COLVIN: On the eve of the Tasmanian state election a Greens Senator has made a claim that challenges the veracity of the Opposition leader Will Hodgman.

Mr Hodgman has spent the past four years saying he won't do a deal with the Greens to form government.

But the Tasmanian Greens Senator Peter Whish-Wilson says that in 2010, when the last state election delivered a hung parliament, Will Hodgman did agree to a meeting with the state's Greens leader to discuss a potential power sharing deal.

Will Hodgman has dismissed the claims as totally false. He says it's desperate politics from the Greens as Felicity Ogilvie reports.

FELICITY OGILVIE: The last Tasmanian state election in 2010 delivered a hung parliament, with Labor and the Liberals winning 10 seats each and the Greens holding the balance of power with five seats.

Labor and the Greens did a deal to form government and the Opposition leader Will Hodgman has always been highly critical of it saying he will never deal with the Greens.

But Tasmanian Greens Senator Peter Whish-Wilson says that after the 2010 election Will Hodgman agreed to meet the state's Greens leader to discuss a potential power sharing deal.

PETER WHISH-WILSON: They were prepared to meet with the Greens for discussion but for various reasons that didn't happen, the main reason being that the Greens had already reached an agreement with Labor. But they were prepared to meet and are prepared to have discussions.

FELICITY OGILVIE: Who was prepared to meet, are you saying that it was specifically Will Hodgman was preparing to meet?

WILL HODGMAN: Completely and utterly untrue. These claims are totally false.

FELICITY OGILVIE: The Opposition leader Will Hodgman says the Greens claim is last minute politics.

WILL HODGMAN: These claims are utterly false and, you know, quite frankly at this stage, at the eleventh hour, literally on the eve of an election, it's desperate politics from a party that has no plan for the state.

PETER WHISH-WILSON: Look, I've been talking about this for four years. It's not a secret. It's not a secret that various Liberal Party MPs in Will Hodgman's own party-room were in negotiations with the Greens to try and get talks happening between him and Nick McKim.

FELICITY OGILVIE: The claim goes to the integrity of Mr Hodgman, who has spent the past four years campaigning for majority government.

A Newspoll in today's Australian newspaper says that the Liberals are on the eve of winning government and achieving Mr Hodgman's goal.

WILL HODGMAN: Look, I'm honestly not concerning myself with public opinion polls when the biggest of all happens tomorrow. All Tasmanians get to have their say and they can choose a majority government that's strong and stable, unified and it's got a plan for this state. Or they can have four more years of the same and that's what they'll get if they vote for the Labor Party, the Greens or the Palmer Party.

FELICITY OGILVIE: The Palmer United Party is a newcomer to state politics and they could pick up at least one seat.

But the ABC's election analyst Antony Green says that the Liberals should still be able to govern in majority even if the Palmer United Party wins a seat in Braddon in the state's north.

ANTONY GREEN: If the Liberal Party gets three seats in Braddon, they'll have three in Bass and three in Lyons and they've got majority government and the party candidate would just be elected and be on the opposition benches.

FELICITY OGILVIE: Based on the opinion polling Mr Green is predicting that the Liberals will win up to 15 seats in the state's 25-seat parliament.

But the Tasmanian Premier Lara Giddings isn't giving up.

LARA GIDDINGS: The polls say one thing but the street says another. So we'll wait and see what happens tomorrow but it will be an exciting day and one where, as a Labor person, I believe all Labor people can hold their head up high.

FELICITY OGILVIE: The Greens leader Nick McKim has already started talking about being in opposition. He recently suggested that his party could win more seats than Labor.

But he's still not ruling out any deals after tomorrow's vote.

NICK MCKIM: We'll have to wait and see how the voters choose to vote when they go to the ballot box tomorrow. Look, what we've been about this campaign is to put forward a positive propositional campaign that backs in Tasmania, believes in Tasmania, backs in Tasmania's competitive strengths - the things that make us unique in the world, and that's been the theme of our campaign and we put that before the Tasmanian people and we let them make their choice.

FELICITY OGILVIE: Analysts are expecting that if the opinion polls are right and there is a big swing to the Liberals in Tasmania a result should be known early tomorrow evening.
